numeric_limits for complex types?

I wonder how this should be handled.

Example: (poor implementation)

template<typename T>
inline T Limit (T x) {
  return (x == T(0)) ? T(0) : x / abs (x);
}

It would be better to test abs(x) < epsilon where epsilon might be
numeric_limits<T>::epsilon, or something to that effect.

But what if T is complex?  One possibility is to specialize Limit for
the complex case.  But is a more elegant approach possible?  Should
complex have it's own numeric_limits?
